Quick, Easy, Accurate and Independent Antifreeze Testing

Antifreeze in sprinkler systems has become a hot-button issue within the sprinkler industry. Recently several incidents have occurred which raised questions regarding the effectiveness and safety of antifreeze solutions in fire sprinklers, particularly residential systems. The National Fire Protection Association (NFPA) committee Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems recommends the following regarding the testing of antifreeze solutions:

  • The system shall be tested annually.
  • If the type of antifreeze cannot be reliably determined, then the system shall be completely drained and replaced with an acceptable solution.
  • The level of antifreeze in solution shall be limited according to the standard.

Why test your antifreeze sample with Dyne Technologies?

  • free antifreeze sampling kit
  • free shipping within the continental (lower 48) United States
  • test reports in 5-business days guaranteed
  • 24 hour turn-around available
  • comprehensive reports
  • tank tags
  • online access to results and forms
  • automatic reminder service to make sure you are always current with your testing requirements
  • immediate communication with our chemists or support staff

 

Antifreeze is typically placed into wet piping sprinkler systems to prevent freezing.  According to National Fire Protection Association (NFPA) 25, if the antifreeze solution is to be tested, a sample should be taken at the top and bottom portions of the system and at the most remote portion of the system if the other two samples do not represent this remote portion.

  • Dyne can determine the type of antifreeze, concentration, and freeze point. 
  • Therefore, even if you do not know what your system has, Dyne can test it against NFPA 25 Standards.

Antifreeze samples that fail are typically caused by one of the following issues:

  • antifreeze solution contains an antifreeze liquid that isn’t allowed by NFPA 25
  • solution is mixed too rich
  • solution is mixed too lean
  • solution is a combination of possible antifreeze liquids

To prevent potential risks, an antifreeze solution that fails should cause the system to be flushed and replaced.

Limit your liability and be sure that your antifreeze solution systems will not freeze by sending them to an independent laboratory for complete testing including a freeze point verification test.
